Patent JP-S61150776-A (JP)
Title: Soldering iron
Inventor: YOGI KAZUMI
IPC: B23K3/02
Filed: 1984-12-25
Abstract: PURPOSE:To improve working efficiency and safety by disposing a shape memory alloy of which the shape changes with a change of temp. near to an iron tip. CONSTITUTION:A cylindrical member 7 provided with a coil 6 made of the shape memory alloy is mounted by a screw 4 to an iron tip holding cylinder 3. The coil 6 is disposed near the iron tip 2 and is kept at the temp. corresponding to the temp. of the tip 2. The compressed coil shape is preliminarily memorized in the coil 6 in the heated high temp. state. The coil 6 is heated when the iron tip 2 is heated while the coil 6 is kept extended in the low temp. state. The coil 6 changes to the memorized compression shape when the coil 6 attains the memorized temp. The visual discrimination of the temp. at the iron tip 2 is made possible by the above-mentioned method. The working efficiency is thus improved and since a skin burn, etc. are prevented, the higher safety is assured.

Abstract: PURPOSE:To reduce a decrease in the coefficient of liner expansion of a sheath material and the release of residual strain and to stabilize transmission characteristics against temperature variation by forming a sheath structure by incorporating specific cut fiber in a specific high polymer material. CONSTITUTION:An optical fiber cable is formed of an optical fiber 1, a high- strength fiber for reinforcement or buffer layer 2, the high polymer material 3, and cut fiber 4 incorporated in the high polymer material. The cut fiber 4 uses glass fiber, ceramic fiber, carbon fiber, aramide fiber, etc., suitably and its elastic modulus is >=4,000kgf/mm<2>. The upper limit of the content percentage depends upon the kind of fiber, but preferably <=70% when the elastic modulus is low, e.g. 4,000kgf/mm<2>. The length of the fiber is preferably <=20mm. Further, the contained fiber is oriented in the direction of extrusion during the extrusion molding of the high polymer material. Thus, transmission characteristics is stabilized against temperature variation.
